Abstract

A trace collection mechanism for recording accesses to a peripheral device (12) having an I/O cache memory (20), comprises a clock (30) and control means (16). At each access of the memory, the beginning and ending times of the access are stored in a part (28) of the cache memory, together with parameters of the access, such as address and length of ac­ cessed data and the type of access. A set of collected data can be analyzed for the operation of both the peripheral de­ vice and the central processing program.
